Yep. Moved to the last patch.

Yes, this works.

Moved to the last patch.

Both of them are redundant, entry->data must be only != NULL.
But I've updated data_end correspondingly:

case MP_MAP:
		if (mp_typeof(*it->pos) != MP_STR) {
			entry->field = NULL;
			mp_next(&it->pos);
			entry->data = it->pos;
			mp_next(&it->pos);
			entry->data_end = it->pos;
			return 0;
		}

Updated patch on branch.
